Before you budget
What Raises or Lowers a Deck Building Estimate
A planning range assumes the house is sound and the ground is easy. These are the things that move a real deck building estimate up or down.
- How high it stands.A raised deck needs deeper footings, heavier posts and more railing.
- The railing, which on a long deck can cost as much as the boards.
- Water.A deck that rotted because water had nowhere to drain needs the drainage solved, not just new boards.

Deck Building Cost Questions
If your question is not answered here, ask our team. A ten minute conversation now is better than a surprise halfway through the project.
Ask Our TeamHow much does it cost to build a deck in Knoxville?
It depends on the size, the decking material, how high the deck stands and the railing. The table above shows typical ranges, and the estimator gives you one for your own deck.
Is composite worth the extra cost over pressure-treated wood?
It costs more up front and much less to keep. Pressure-treated wood needs sealing every few years, while composite holds its color with little more than a wash.
Can you rebuild a deck that has rotted?
Yes. In Farragut, a deck had rotted because tile ran out onto it with nowhere for water to drain. The covered part was rebuilt with a seamless cut, the open part moved to composite, and it gained new railings and steps with lighting wired into each one.
Does a deck need a permit?
Most raised decks do, and requirements depend on where the home is. The estimator includes a line for permits and inspections.
How much does a composite deck cost?
More than pressure-treated wood up front, and far less to keep. The table above shows composite decks at two sizes, and the estimator prices yours.
How much does it cost to replace an old deck?
Close to the cost of a new one, plus tearing out the old deck. The estimator adds the tear-out as an option, and if rot was the reason, the drainage gets solved too.
